This is a rather silly article. There is absolutely nothing wrong with how OSX installs software on the MAc. I don't want the installer to ask me if I want to make Firefox default. You can leave that crap on Windows, I know how to make it default. However Firefox is so slow compared to Safari I just I just moved to Safari full time anyway.

Either way don't fix what isn't broken. When you first download the package from the internet (assuming you are using safari), the dmg mounts automatically mounts unless otherwise specified and if a user is too stupid to read "drag here", then they don;t deserve a computer in the first place. Basically your article reads like you want the installer to work like it does on windows. OSX is not windows, its install process is much simpler and easier to manage.
